Electronic leak detection in Woodmansterne
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help because they show what’s under the surface. We will tell you if the roof cannot be tested. If you’ve noticed water coming in under a flat roof and breaches hidden under paving or planting, a survey will tell you what’s going on, on commercial flat roofs, liquid-applied waterproofing and single-ply roofs alike.
Outbuildings, garden rooms and garages in places like Woodmansterne frequently have flat roofs of their own. They’re rarely looked at until something gets wet. If you want them looked at too, mention them as you book, along with the main flat roof. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, each with a short note and a photo. You’ll see the good as well as the bad.

What affects the price in Woodmansterne
Prices always include VAT. The things that change the price are:
- Commercial roofs and larger buildings
- Any need for thermal images or a drone flight
- Building height and the viewpoints available
- Features like valleys, chimneys, dormers and parapets
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.
What to let us know when you contact us
To price your survey accurately, we will ask about:
- What kind of property and roof it is
- Where any leaks, stains or damp patches show inside
- Whether there’s a loft hatch, a shared roof or tricky access
- The reason for the survey, such as buying, a leak or storm damage
To book a survey, phone 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.
What electronic leak detection does not cover
Every survey has limits, and we’d rather be clear about that before booking. Bear these in mind:
- Build-ups without a suitable layer below
- Moisture spread under the membrane
- Parts of the roof covered by fixed equipment
If in doubt, phone 07833 053749 or email us and we’ll point you to the right survey. What a survey covers and does not.
Roof types and parts we check
- Flat roof membranes
- Commercial flat roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
- Green roofs
- Single-ply roofs
For landlords and managing agents
Businesses and commercial landlords can book us too. Bigger roofs take more time, and they’re priced for the size.
An agent can book and manage the survey for a landlord, and the report can go to both. Access is agreed with the tenant ahead of time.
How the survey changes by roof type
EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We will tell you if yours isn’t suitable.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.

How it works
A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from every safe vantage point, photograph what we find and record our findings for the written report. It normally takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. In a smaller place like Woodmansterne, as anywhere, the forecast plays a part: drone flights and thermal imaging need the right conditions, while a look from ground level and the loft can go ahead in most weather.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before we arrive
- Clear the way to the loft hatch
- If it isn’t your property yet, arrange access through the agent
- Have keys ready for side gates, garages or roof access doors
Book a survey
Our phone lines are open seven days a week, including Saturdays and Sundays. For a price or to book, phone 07833 053749 or email us.
Related advice
Before and after the survey
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Do not leave water getting in
- Keep foot traffic on flat roofs to a minimum
- Have roof specifications to hand
- Keep a note of leaks after rain
Wet insulation may need attention after a leak. That’s something to discuss with your roofer and other checks can help judge it.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
FAQs for Woodmansterne
Is Woodmansterne within the area you cover?
Yes. Woodmansterne is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and South East England. Just mention lanes, gates or anything else about the route when booking.
Does a conservation area affect roof work in Woodmansterne?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We look at the roof, not the whole building, and it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
Can you survey at the weekend?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days as you book.
Do you look in the roof space?
Yes, where the survey calls for it and there’s safe access. Inside, we look for damp, staining, gaps and sagging.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is frequently shared, so we need permission from the freeholder or managing agent. We inspect only the parts we are allowed to reach.
What insurance do you have?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
Flat roofs in Woodmansterne
Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. With Nonsuch Mansion about 3.9 miles north-west, Woodmansterne sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
If you let a flat or house near Chipstead station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For an older house near a landmark like St Peter's Church, the joins between later flat roofs and the old walls are where problems normally start. Anyone responsible for a site like Chipstead Valley Primary School will know that a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.
